the ability to perceive and understand an object through touch, its size, shape and texture

Question 13

visceral

Answer 13

large organs within the body

Question 14

stimulus

Answer 14

an agent or act that stimulates a nerve receptor

Question 15

receptor

Answer 15

a nerve cell that acts as a receptor by converting the stimulus to an impulse

Question 16

impulse conduction

Answer 16

act of an impulse traveling along a nerve pathway to the spinal cord or directly to the brain

Question 17

awareness

Answer 17

ability to perceive environmental stimuli and body reactions and then respond

Question 18

myopia

Answer 18

near sighted

Question 19

hyperopia

Answer 19

far sighted

Question 20

cataracts

Answer 20

breakdown in protein in lens. results in lens not being able to change shape to focus

optic neuropathy w/ gradual loss of peripheral vision

Question 22

age related macular degeneration

Answer 22

loss of central vision due to retina damage

Question 23

peripheral neuropathy

Answer 23

occurs when trauma or disease processes interfere with innervation of peripheral nerves

Question 24

Risk factors for impaired sensory perception

Answer 24

age
chronic disease 
eye/ear trauma 
ototoxic drugs
environmental/occupational exposure

Question 25

physiological consequences of impaired sensory perception

Answer 25

potential safety issue | decreased ability to perform ADLs

Question 26

define amblyopia

Answer 26

lazy eye

Question 27

conductive hearing loss | most common cause

Answer 27

anything that disrupts the transmission of sound from external ear to inner ear. most common cause is obstruction of the external ear canal.

Question 28

sensorineural hearing loss

Answer 28

disorders that affect the inner ear, the auditory nerve or the auditory pathways of the bran. soundwaves are transmitted to inner ear but damaged receptors are unable to receive and interpret stimuli

Question 29

screening periods across lifespan for hearing

Answer 29

Newborns:before they leave hospital preschool/school age: periodically at well child visits adults: every 10 years >50: every 3 years

screening periods across lifespan for vision

Answer 30

``` 3-5 years: at least once Exam at 40 40-54: every 2-4 years 55-65: every 1-3 years >65: every 1-2 years ```
